摘要
为了精确测量奥克托今（HMX）基高聚物粘结炸药（PBX）冲击起爆过程的Lagrange粒子速度随时间的变化，采用与炸药阻抗匹配的铝基组合电磁粒子速度计实验技术，测量了3．07，4．14，7．81，8．12GPa入射压力下某HMX基PBX炸药样品中的Lagrange粒子速度随时间的变化。结果表明：铝基组合电磁粒子速度计时间响应快，感应单元冲击响应上升时间为20ns。不同起爆压力下获得HMX基PBX炸药样品中1～8mm深度处的Lagrange粒子速度随时间变化响应快、干扰小。
In order to accurately measure the change in Lagrange particle velocity with time in the shock initiation process of HMX- based PBX, AI-based electromagnetic particle velocity gauge technique was used to measure the change in Lagrange particle veloc- ity with time history in HMX-based PBX samples under the incident shock wave pressure of 3.07,4.14, 7.81 GPa and 8.12 GPa. Results show that the time response of AI-based electromagnetic particle velocity gauge is very fast and the rising-up time of impact response for induction unit is less than 20 ns. The time response for the change in Lagrange particle velocity with time at 1 -8 mm depth position of HMX-based PBX obtained under different incident shock wave pressures obtained is fast and the interference is small.
